SHOW-CASE CORNER FASTENER.

Application filed April 17, 1922. -Serial No. 553,595;

To all whom t may concern:

Be it known that I, HARRY C. SCHLUETER, a citizen of the United States, residing in the city of St. Louis, Stateof Missouri, have invented a certain new and useful Improvement in Show-Case Corner Fasteners, of which the following is a specification.

My invention relates to corner fasteners for plate-glass show cases, and, is a distinct and practical improvement to overcome `certain practical objections to, and defects in, corner pieces of the type making it necessary to drill holes in the glass to receive screw fasteners.

The object of my present invention is to provide an upper corner plate including an inner cushion member` capable of being drawn tightly into contact with the inner face of two upright glass panels .and a horizontally disposed panel for firmly holding the panels position at their .corners between the corner plate and the cushion member.

A further object of the invention is the ,provision of ascrew-threaded-member for drawing the cushion member in operative position. v I Y A' further object of the invention is to provide a lower corner plate adjustably connected to the floor of the show case to accommodate any thickness of glass panel between the outer faces of the floor and the vwalls of the lower corner plate.

A still further object of the invention is ftheprovisi-on .of a tie-rod for connecting the cushion member :of the upper corner plate with 4the lower corner plate to prevent any -possible chance of the upright panels being lifted out of their corner sockets.

lWith the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described a-nd finally point-ed out in the claims hereto appended.

Referring to'the accompanying drawings forming -a part of this speciication, wherein like characters of reference denote similar parts throughout the several views:

. Fig. 1, is a vertical sectional view of the upper and lower corners of a glass panel embodying' my inventi n.

Fig. 2, is a plan view of the upper cornery of a show case employing my corner fasteners.

Fig. 3, is a perspective view of the upper corner of a show case provided with my corner fastener.

Fig. 4, is a plan view of the cushion, or binding member which co-acts with the upper cornery plate showing its engaging faces.

Fig. 5, is also a plan view of the cushion member.

Fig. 6, is a sectional view of the cushion member.

Fig. 7, is a top, plan view of the lower corner plate fixed to a show case corner.

Fig. 8, is a bottom plan view thereof.

Referring to the accompanying` drawings, the reference character 1 represents the door of a show case, 2 the yfront glass panel, 3vthe end, or side glass panel vand 4 the top glass panel, which glass panels meet to form an upper corner, as shown in Figs. 1, 2 and 3, and, which glass anels 2 vand 3 and the floor meet to form t le lower corner of the show case, yas shown in Figs. 1, 7 and 8.

5 indicates an upper cornelplate having three walls so as to appear polygonal in shape. The walls of the corner plate, it

show case provided wth corner fasteners will thus be seen from Fig. 3, will engage three glass panels, namely, the front panel 2, the end panel 3 and the top panel 4. The pl-ate 5 is provided with an opening 6 at its apex, as shown in Fig. 1.

7 indicates a polygonally vshaped cushion or binding member having the three triangular sides, or faces S, 9 and 10 ter-minating in a truncated end, Aor apex 11. The cushion member 7 is provided with a central opening 12 terminating at the base of lthe cushion member in a socket 13. The cushion member is also provided with a channel 14 which communicates with the opening 12 and the socket 13, as clearly shown in Fig. G. The three faces 8, 9 and 10 of the cushion member are each provided with `the yieldable facings 15, 16 and 17, respectively, such as cork, rubber, or the like. These facings may be suitably xed to the faces of the cushion,y member, as is manifest. The cushioned faces of the cushion member 7 engage the inner faces of the glass panels 2, 3 and 4, as is evident from Figs. 1 and 2 of the drawing.

18 indicates a suitable screw, which is provided at its outer end with a head 19 for engaging the apeX of the corner plate 5.v The screwv18 passes through the opening 6 of the corner plate land through the opening 12 of the cushion member 7 and is provided with a nut 2O at its inner end which is seated in the square socket 13 in the base of the cushion member to prevent the nut from turning whenever the screw is turned in either direction. It is evident that when the screw is turned in one direction, that it will draw the polygonally shaped cushion member tightly against the inner faces of three glass panels, thereby firmly holding the upper corner of the show case in proper position and alignment, as will be observed from Figs. 1 and 3. 'Io permit the entrance of the screw into the opening 12 of the cushion member, it is only necessary to break away the extreme corners of the three glass panels, as at 21, to provide the necessary passage for the screw. By this arrangement, it obviates the necessity of drilling holes in the glass panels to receive fastening devices, such as screws, which ar-e usually employed.

- 22 indicates the. lower corner plate which also has three sides, or walls, so as to appear polygonal in shape. This corner plate 2.2 has one of its walls engaging the lower face of the floor 1 of the show case and is held in position by means of a bolt 23 which passes through an opening 24 in one wall of the corner plate and extends upwardly througha slotted opening 1 in the corner of the ioor 1. The bolt is provided with a head at its lower end which is seated in the counter sunk opening 25 ofa bar 26 and the upper end of the bolt is provided with a washer 27 and a nut 28 for firmly locking the corner plate in its adjusted, or proper position with relation to the iioor 1 and glass panels 2 and 3. The upright side walls of the lower corner plate 22 are spaced a suitable distance from the side or outer .faces of the floor 1 to provide the sockets 29 and 30 for the glass panels 2 and 3, respectively to stand in, as is evident from Fig. 7. The slotted opening 1 of the floor 1 permits proper adjustment of the lower corner plate before tightening the nut 28, as is manifest. The bar 26 is held from rotary displacement by means of the bolt 31 which also anchors the bolt or screw 237 as shown in Figs. 1 and 8.

To prevent any possible chance of some one lifting up on the top plate 4, or lifting the side and front panels from their sockets 65 and 30, respectively, should the panels be at all loosely held therein, I provide a tie-rod 32having a hook shaped upper end 33 adapted to engage in the channel 14 of the cushion member 7. The tie-rod 32 eX- tends downwardly at the corner of the front and end panels 2 and 3 and the lower screwthreaded end 34 thereof passes through the slotted opening 1 of the floor and is provided with a shoulder nut 35 which engages the counter sunk opening 36 of bar 26 and passes through the opening 24 of the lower wall or side of the lower corner plate 22.

By tightening nut 35 it will be observed that the upper and lower corner plates are substantially tied together so that there is no danger of the front and side glass panels being lifted from their sockets between the floor 1 and the walls of the lower corner plate. v

From the foregoing description, it is evident that by the use of ymy improved corner plates and associated parts, that I eliminate the boring of any holes in the glass panels and keep the glass panels in exact relation to form a true corner. A glass show-case employing my improved corner plates and fasteners, it will be observed, can be quickly set up without the assistance of skilled labor, as no boring of holes is necessary.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

I do not wish to be understood as having limited myself to the eXact details of construction shown and described, but desire to have it understood that the invention I have shown in the drawings is merely illustrative, as it is manifest that various* minor changes maybe made in the exact construction and particular arrangement of parts without departing from the spiritof my invention, hence I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.

Whatk I claim is: l,

1. In a glass panel show case corner fastener, in combination, a triangular lower corner plate having at walls, a show case floor member having a corner slot with one end open, and a bolt passing upwardly through the lower wall of the corner plate and directed upwardly through the slotted means for holding said corner plate and said binding member in engagement with the outer and inner faces, respectively, of the front, end and upper glass panels of the 5 show case, a lower outer corner plate, means for holding said corner plate in spaced relation with the floor of the show case to provide sockets for the front and end glass panels of the show oase and means for connecting said upper and lower outer corner plates.

In testimony whereof, I have hereunto signed my name to the specification.

HARRY C. SCHLUETER.
